[coreboot] MSI 890-GXM-G65 (MS-7642) support / any interested users?

[Harald Gutmann]

Hello!

I recently bought the above mentionend mainboard and it is used in my new 
desktop computer.

As I used bevore the Gigabyte M57SLI-S4 I'd really like to see coreboot 
support again on my new mainboard.

Actually I'm not fully up to date with the shape of coreboot and it supported 
components but I think it should be possible to get this board working with 
coreboot.

Matthias Mattsson asked for coreboot support of this mainboard some while ago, 
but these days the SB880 was supported. I think now this platform should be 
supported.

The recent flashrom version finds the following:
Probing for Winbond W25Q16, 2048 kB: probe_spi_rdid_generic: id1 0xef, id2 
0x4015
Chip status register is 00
Found Winbond flash chip "W25Q16" (2048 kB, SPI) at physical address 0xffe00000.

Therefore I guess that flashrom support should be fine, but it is as of now 
untested.

lspci gives the following components:

This should be an RS880/RS890 northbridge. The processor is fam10h.


Can anyone give me a statement if there is already a similar board working or 
which board would be the best starting point to look at?

Any hints and recommendations are welcome.



Kind regards,
